[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0023] Example

[0024] like Figure 1 As shown, an arthroscopic fan-shaped reverse bite basket forceps includes a forceps rod 1 and a forceps mouth; a channel 2 is provided in the forceps rod 1, and a control line 3 is provided in the channel 2; the forceps mouth is provided at the front end of the forceps rod 1; the forceps mouth includes a fixed forceps 7 and a movable forceps 8; the fixed forceps 7 is fixed to the front end of the forceps rod 1, and a jaw 6 is provided on the side of the fixed forceps 7, and the rear end of the movable forceps 8 is an arc-shaped edge; the movable forceps 8 is adapted to the jaw 6, and the movable forceps 8 is relatively hinged to one end of the fixed forceps 7 away from the forceps rod 1, and the movable forceps 8 is connected to the control line 3, and the control line 3 drives the movable forceps 8 to open and close relative to the jaw 6.

[0025] Beneficial effects of the utility model:

[0026] The backward setting of the jaws 6 adopted in this solution can make it more convenient to cut the meniscus, and the arc-shaped edge at the rear end of the movable clamp 8 can better adapt to the inner edge of the meniscus, can better bite out the natural shape of the meniscus, and is more convenient to use.

[0027] The front end of the movable clamp 8 is hinged with the fixed clamp 7, and a torsion spring is provided at the hinge between the movable clamp 8 and the fixed clamp 7, and the torsion spring drives the movable clamp 8 to open relative to the fixed clamp 7, and the control line 3 is connected to the middle of the movable clamp 8. The movable clamp 8 is kept in a relatively fixed and open state by the torsion spring, and when it is necessary to close and bite, the control wire is pulled to drive the movable clamp 8 to close relative to the fixed clamp 7, so as to achieve the effect of biting tissue.

[0028] Combination Figure 2 As shown, the width of the end of the jaw 6 away from the clamp rod 1 is smaller than the width of the end close to the clamp rod 1. The area of ​​the meniscus that can be bitten is larger, and the operation is more efficient.

[0029] The jaws 6 are fan-shaped, which can better adapt to the natural shape of the meniscus and make the biting more efficient.

[0030] A wire groove 5 is provided on the back of the fixed jaw 7, one end of which is connected to the hole 2, and the other end of which extends to the front end of the jaw 6. The front end of the control wire 3 is connected to the movable jaw 8 through the wire groove 5. This prevents the control wire 3 from interfering with the movement of the movable jaw 8 in the jaw 6.

[0031] A silicone ring 4 is arranged between the front end of the channel 2 and the control line 3 to prevent tissue from entering the channel 2.

[0032] Example 2

[0033] Combination Figure 3 As shown, compared with the embodiment 1, this embodiment also includes the following distinguishing technical features: the jaws 6 are arranged to pass through the fixed insert in front and behind, so as to increase the range of movement of the movable jaws 8 and enable better bite of tissues.

[0034] It should be noted that, like a meniscus repair blue pliers disclosed in patent document with publication number CN116058925A, this solution, compared with the existing articular basket pliers, only changes the front end part of the pliers rod 1, and does not change the rear end handle part. The existing handle can be directly used, and the opening and closing action of the movable pliers can be driven by pulling the control line.

[0035] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
